云服务器Centos或linux下安装zookeeper

雨点打透心脏的1/2处 2022-05-06 04:00 236阅读 0赞

1、xftp上传zookeeper到指定文件夹下  
2、解压：`tar -xvf zookeeper-3.4.6`  
3、切换到解压后的zookeeper-3.4.6文件夹下，新建data和logs文件夹，  
并将zoo\_sample.cfg导出到本地win电脑，改名为zoo.cfg.  
![zk配置0][zk_0]  
将zoo.cfg里配置如图后上传conf：  
![zoo.cfg配置][zoo.cfg]

dataDir=/root/zk/zookeeper-3.4.6/data
    dataLogDir=/root/zk/zookeeper-3.4.6/logs

4、执行`vi /etc/profile`,  
insert下配置用户环境变量:

#zookeeper env 
    export ZOOKEEPER_HOME=/root/zk/zookeeper-3.4.6
    export PATH=$ZOOKEEPER_HOME/bin:$PATH

使修改生效：`./etc/profile`或`source /etc/profile`

报错：

Error contacting service. It is probably not running.

![zk\_failed][zk_failed]  
解决办法：  
1、检查zoo.cfg配置文件  
2、修改目录权限，如将usr下的权限修改：

sudo chmod -R 777 /usr

3、将其安装在root路径下试试

5、启动zookeeper：  
切换到bin目录下，/root/web/zookeeper/zookeeper-3.4.6/bin

启动：`zkServer.sh start`  
查看zookeeper状态: `zkServer.sh status`

重启 zookeeper 服务：`zkServer.sh restart`

6、启动成功信号：

Starting zookeeper ... STARTED
